Spring constant of a spring is calculate...

Spring constant of a spring is calculated using formule `K=(4pi^2M)/T^2`, where T is time period of vertical oscillation when mass M is hung with the help of spring to rigid support. If time of oscillation for 10 oscillations is measured to be 5.0 s and mass M=0.20 kg, find possible error in spring constant K.
